Detection of Brucella in Dermacentor Ticks of Wild Boar with Brucellosis

Figure 1

Brucella suis biovar 2 transmission. B. suis biovar 2 persists in wild boar (Sus scrofa) and domestic swine as the primary reservoir hosts, with direct vertical transmission to offspring. Horizontal transmission occurs from wild boar to livestock, humans, and probably other wildlife species. Dermacentor ticks are a reservoir for Brucella suis biovar 2 and may contribute to its spread among wild boar and potentially other wildlife species, livestock, and humans. Transovarial and transstadial transmission has only been demonstrated for B. melitensis and B. abortus in D. marginatus or D. nuttalli. The contribution of the environment in B. suis biovar 2 has only been proved for domestic swine.
